RV Mirror w/Thermometer, compass, & auto-dimming. 1-line display. Complete with sensors, wiring pigtail, & mounting button, tested working.
"If the temperature sensor is short- or open-circuited, the display will read SC or OC, respectively, instead of a temperature. If the temperature drops below 3.3�C (38�F) or is below 3.3�C (38�F) upon power-up, the display will alternate between displaying "ICE" and the temperature. The display will alternate every two seconds for a time of one minute."
